Jump-Over Hose

Flexible Metal Jumpover Hose

Flextrol also provides jumpover hoses to interconnect the numerous jackets in a jacketed piping system. These hoses are available in standard diameters of 1/2″, 3/4″ and 1″ male NPT pipe. Jumpover hoses are made from stainless steel flexible hose, and can be insulated with fiberglass/silicone covers. Standard lengths include 24″,28″ and 30″ with other lengths available.

The Illustration shows how jumpover hoses interconnect jacket sections in series. The photograph shows a typical valve jacket to pipe jacket connection.

Flex-C-Loop Hose

Absorbs movement from thermal expansion/contraction and seismic activity.
Custom-designed for specific movement requirements.
Compact design requires less space than hard pipe loops — ideal for indoor use.
Produces zero thrust loads (unlike metal bellows or rubber expansion joints).
Low spring rates reduce need for large anchors and excessive pipe guides.
Flextrol provides thermal movement calculations upon request.

PTFE SB Hose

PTFE (Teflon) and FEP Lined Hose

Designed to handle challenging media including chemicals, steam, solvents, inks, dyes, paints, injectable materials, and plastisols.
Used across many applications including Applications: Sanitary transfer, bottle filling, gas analysis, extrusion presses, molding/adhesive conveying.
Jacketed PTFE and FEP hose is also available.
Liner Options: Nominal smoothbore, standard smoothbore, or convoluted.
- Non-conductive (white) and conductive (black) options
Cover Options: Stainless steel braided, EPDM rubber covered, braided with silicon cover, polypropylene braided, or PVDF braided.
Sizes Available:
- Braided Smoothbore: 3/16”-1”
- Rubber Covered Smoothbore: ½”-4”
- Convoluted: 3/8”-2”

FEP Rubber Covered Hose

Rubber Covered
Fluoropolymer Hose

Smooth bore fluoropolymer tube is internally bonded to multiple polyester ply cords and EPDM rubber reinforcement, then further strengthened with a high tensile strength carbon steel wire support. The EPDM rubber hose cover is ozone, abrasion and chemically resistant. While our standard color is green, this rubber cover is available in different colors which can help you identify specific process lines or trace it by department.

Features:

Unsurpassed chemical resistance
Easy to clean
- Assured sterility
- Non-stick smooth tube
- Can be cleaned with steam, caustics, solvents, or other cleaning agents
Durable, kink resistant with non external wire reinforcement
Full vacuum rated
FDA approved
Temperature rating: -40ºF to 350ºF

PTFE Convoluted Hose

Convoluted Fluoropolmer Hose

A convoluted fluoropolymer hose has a heavy inner wall of fluoropolymer with a stainless steel or polypropylene outer braid. The convoluted inner tubes are low profile and have a helical formed shape which promotes draining. These types of hoses are used in chemical plants, food processing and pharmaceutical companies, petrochemical sites, pulp and paper processors and general industrial companies of all types. The temperature ratings for these hoses range from -65ºF to 400ºF.

Interlock Metal Hose

SMOOTH BORE INTERLOCK HOSE

ROUGH BORE INTERLOCK HOSE

Interlocked Metal Hose

Interlocked hose is used for specialized industrial applications and is available in different metals, sizes, and styles. Interlock is a term used with flexible metal hose meaning the hose winding is mechanically locked together and cannot come apart unless the metal is yielded. Adjacent edges are folded together to form the interlocked convolutions.

To make sure the hose is pressure tight or to minimize leakage, a packing material may be inserted into the preformed groove within the interlock.

The packing acts as a gasket seal along the entire length of the hose. Interlocked metal hose is extremely flexible and light weight. The sliding action that the hose makes is what provides the flexibility. When the convolutions on the outside of the hose are fully open, and the convolutions on the inside are fully closed, the minimum bend radius is achieved. Should the hose be forced upon its limits, it will deform permanently. Pressure tight hose is significantly less flexible because the packing material produces a greater resistance to the sliding action.
